I get a large majority of my brewing-related info from online forums, especially BrewBoard and Northern Brewer. But I also read BYO and The New Brewer magazines every issue, and I have a large collection of Brewing Techniques and Zymurgy as well. And I read brewing books, both for homebrewers and pros. You can never have too much information!

Oh, and brewing podcasts, like The Brewing Network (The Sunday Session and The Jamil Show) and Basic Brewing Radio/Video are great.

I voted "a brewing forum online", because I could only vote for 1 thing.

In fact, I should probably say J.Palmer's "How to Brew" (and howtobrew.com) (and to a lesser extent, Designing Great Beers), a brewing forum (primarily brewboard.com, but also forum.northernbrewer.com), fellow brewers I know in person (including brewshop owners that give me info that I seem to have to take with a grain of salt), Jamil Z.'s show on the Brewing Network, and Brew Your Own magazine. Pretty much in that order.

I still haven't made the time for Basic Brewing, I'll definately give that a try. Sometimes I'll listen to the Sunday Show's archives while I'm brewing, but 3 hours for a show that could be editted down to about an hour of actual information tries my patience. But there have been some great guests on the Sunday Show (The White Bros., J. Palmer, Denny Cohn!).
